Swift UITableView Cell Selection not working after search result - ios

Question

My Scenario, I am trying to Implement UITableview with custom cell and search option. Here, Search working fine but I cant able to select search result particular row. How to fix this also please check below my code is fine for search option Integration. If anything idea about code simplification, Please provide some sample.
My Code Below
class CustomCell: UITableViewCell {
#IBOutlet weak var nameLabel: UILabel!
}
class ViewController: UIViewController,UISearchControllerDelegate, UISearchResultsUpdating, UISearchBarDelegate, UITableViewDelegate, UITableViewDataSource {
var searchController : UISearchController!
let data = ["New York, NY", "Los Angeles, CA", "Chicago, IL", "Houston, TX",
"Philadelphia, PA", "Phoenix, AZ", "San Diego, CA", "San Antonio, TX",
"Dallas, TX", "Detroit, MI", "San Jose, CA", "Indianapolis, IN",
"Jacksonville, FL", "San Francisco, CA", "Columbus, OH", "Austin, TX",
"Memphis, TN", "Baltimore, MD", "Charlotte, ND", "Fort Worth, TX"]
var filteredData: [String]!
let cellReuseIdentifier = "cell"
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
filteredData = data
}
#IBAction func searchAction(_ sender: Any) {
// Create the search controller and specify that it should present its results in this same view
searchController = UISearchController(searchResultsController: nil)
// Set any properties (in this case, don't hide the nav bar and don't show the emoji keyboard option)
searchController.hidesNavigationBarDuringPresentation = false
searchController.searchBar.keyboardType = UIKeyboardType.asciiCapable
searchController.searchBar.barTintColor = #colorLiteral(red: 1, green: 0.5763723254, blue: 0, alpha: 1)
searchController.searchBar.backgroundColor = #colorLiteral(red: 1.0, green: 1.0, blue: 1.0, alpha: 1.0)
// Make this class the delegate and present the search
self.searchController.searchBar.delegate = self
searchController.searchResultsUpdater = self
present(searchController, animated: true, completion: nil)
}
// number of rows in table view
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.filteredData.count
}
// create a cell for each table view row
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:CustomCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as! CustomCell
cell.nameLabel.text = self.filteredData[indexPath.row]
return cell
}
// method to run when table view cell is tapped
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let cell = tableView.cellForRow(at: indexPath) as! CustomCell
print(cell.nameLabel?.text! ?? "")
//self.tableView.selectRow(at: indexPath, animated: true, scrollPosition: .top)
}
func updateSearchResults(for searchController: UISearchController) {
if let searchText = searchController.searchBar.text {
filteredData = searchText.isEmpty ? data : data.filter({(dataString: String) -> Bool in
return dataString.range(of: searchText, options: .caseInsensitive) != nil
})
tableView.reloadData()
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}

Answer 1

Swift 5 (iOS 12+)
searchController.obscuresBackgroundDuringPresentation = false

Answer 2

The Problem is inside cellForRowAt
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:CustomCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as! CustomCell
cell.nameLabel.text = self.filteredData[indexPath.row]
return cell
}
Update Above Code with Following Code :
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:CustomCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier, for: indexPath) as! CustomCell
cell.nameLabel.text = self.filteredData[indexPath.row]
return cell
}

Answer 3

We can solve this by using below code.
The problem is dimsBackgroundDuringPresentation
searchController.dimsBackgroundDuringPresentation = false
